Abstract:
This study is the first on the response of Aleppo 124 Variety to different planting dates, where the research aimed to study the response of some productive and morphological characteristics of Aleppo 124 variety to different planting dates. The experiment was carried out in 2020 and 2021 at the Scientific Agricultural Research Center in Hama of the General Authority for Scientific Agricultural Research, which is located 4 km south and 316 m above sea level, which is characterized by an annual precipitation rate of 338 mm/year. The experiment was designed according to a random block design, and the results were analyzed according to the Genstat 12 statistical program. The result of the analysis of variance (ANOVA) at a significant level of 5%, showed that there were high significant differences in the yield of the beloved cotton of the variety Aleppo 124 between the studied planting dates, where the planting date (14-19 of May) outperformed (3812 kg/h) in productivity over The productivity of the subsequent planting dates. It was found that a week’s delay from this date led to a decrease in productivity that ranged between 650 and 850 kg/ha. There was also a significant superiority for plant height, number of fruiting branches and chlorophyll number, higher and middle of the plant over the other later dates. It is possible to extend the planting date of Aleppo 124 variety until the first third of May in Hama.
